Off Grid Solar Batteries Aren&#;t Just for Camping

Years ago, solar batteries had their habitat in remote campsites and mountaintop cabins. Today, they&#;re still essential for boondocking and dry camping but with &#;grid defection&#; on trend, solar setups are making their way towards many towns and cities.

People are going off grid in places where grid power is available. They&#;re building eco-friendly tiny houses that completely rely on solar power. Others are installing solar panels on rooftops as backup power in places where the grid&#;s frequently unreliable. Some are saving big money by using solar only, and relying on the grid as a backup.

So now, more than ever, off grid batteries need to be reliable, long-lasting, and efficient. But not all batteries are created equal. Below, we&#;ll discuss the different types of off grid solar batteries so you can decide which is best for you.

What Are the Best Batteries for Solar Off-Grid Use?

There&#;s no denying that lead acid batteries have been used in off grid solar setups for a long time. They&#;re the &#;OG&#; (original) batteries, and in the early days of solar energy, you wouldn&#;t see a setup without them.

But technology has evolved since then. So while your average lead acid battery can get the job done, we wouldn&#;t say they&#;re the best off grid solar batteries on the market. They may be the most affordable up&#;front, but their benefits don&#;t go far beyond that.

Now each battery type has its pros and cons. We&#;ll compare the top contenders for off grid solar batteries, specifically lead acid, AGM, sealed gel, and lithium. But first, a brief word on what to look for, regardless of the battery type.

Keep the following in mind as you shop for the best option for you:

• DoD (Depth of Discharge) is basically how much energy you can expend before the battery starts to slowly take damage (this shortens the lifespan). So to get more usage from your battery&#;s capacity, you&#;ll want a battery with a higher DoD.
• The battery&#;s capacity is the amount of electricity it generates (measured in kWh). Most off grid and solar batteries have a capacity in the neighborhood of 10kWh, and most houses in the US use around 30 kWh per day.
• A battery&#;s power is its output; the amount of power it can put out in kilowatts (kW).
• Last but not least is your battery&#;s round trip efficiency. This basically shows you the difference between the energy you used to charge the batter, and the total energy available to use in the battery. The higher the percentage, the better and more valuable the battery is.

Now that we&#;ve covered that, it&#;s on to the pros and cons of each battery type. These are the four most popular solar batteries available today and that&#;s why each is worth discussing. So let&#;s get to it!
